Is the pay worth it?

It's called being employed. We all listen to someone pissing and moaning. If it's affecting your mental health, however, I'd seek out a therapist.

That's half of my job. I hate it, especially when she calls and messages after hours

At least you get paid. Most people have to listen to that crap for free.

Me too! I work with my boss and one other guy and he literally complains about #2 almost every day MON-FRI. He'll go on for 5-15 minutes and I just nod and agree when he talks smack 😂

That sounds like good money.
